CMS-50E OLED Rechargeable Fingertip Pulse Oximeter

Product Review (submitted on June 27, 2019):

I purchased the 35" OLED pulse oximeter so that I could monitor and record my blood oxygen levels whenever necessary at home. In the passed I either had to use the one in my doctors office or borrow one for overnight. This device offers an excellent and inexpensive way to check levels at my convenience."
